IMAP Fixes & Improvements (#13582)

- Removed caching of IMAP client as it was problematic and didn't really
matter because of our pipeline, also added retry logic to client.
- Some code refactoring and cleanup
- Breaking changes:
   - Removed messageChannel.syncCursor
   - Uses messageFolder.syncCursor instead
- Removed Date based sync cursor in favor of message UID which is much
more reliable and precise
